Given numbers are 639,699,946,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,699,946,946 is 140847102.
Find LCM of 639,699,946,946 with Prime Factorization
| 2 | 639, 699, 946, 946 |
| 3 | 639, 699, 473, 473 |
| 11 | 213, 233, 473, 473 |
| 43 | 213, 233, 43, 43 |
| 213, 233, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 213 x 233 x 1 x 1 = 140847102
Therefore, the lowest common multiple of 639,699,946,946 is 140847102.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
639 x 699 x 946 x 946 = 399724075476
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
639 : 1, 3, 9, 71, 213, 639
699 : 1, 3, 233, 699
946 : 1, 2, 11, 22, 43, 86, 473, 946
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,699,946,946, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
699:3x 233
946:2x 11x 43
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 43 = 2838
Therefore, the value for common factors is 2838.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 399724075476/(1x2838)
LCM = 399724075476/2838
LCM = 140847102
Thus, we can understand that the LCM of 639,699,946,946 is 140847102.
